View 1 RepliesHow To Check A SQL Database Table To See If A Record Exists?
May 10, 2010I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.
I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.
Does that make sense?
Using myConnectionCheck As New SqlConnection(myConnectionStringCheck)
Dim myCommandCheck As New SqlCommand()
myCommandCheck.Connection = myConnectionCheck
myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName
myConnectionCheck.Open()
myCommandCheck.ExecuteNonQuery()

View 1 RepliesAJAX :: Check Whether A Particular Record Exists In Database Using JQuery
Aug 18, 2015I have a asp:Button and asp:Textbox on Default.aspx page
Code is as below:
<asp:Button ID="Button1" runat="server" Text="Save" Width="80px" CommandName="Update"
OnClientClick="EnableDdlCompany();saveButtonClick();" CommandArgument="Save" OnClick="btnSave_Click"/>
<asp:TextBox ID="txtBarcodeNumber" runat="server" MaxLength="11" Width="230px"
Text='<%# Bind("BarcodeNo") %>' Display="None"
OnTextChanged="TextChanged" AutoPostBack="true"></asp:TextBox>
On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx
I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:
protected void TextChanged(object sender, EventArgs e) {
TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox;
if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) {
string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character.";
ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);
[Code] ....
Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file
But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.
That's why I want to achieve it using Javascript.

Dec 7, 2010What is the way to :

View 1 RepliesForms Data Controls :: Check If A GridView Exists?
Dec 9, 2010I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.
Web Forms :: Check If Child Node Exists On Treeview?
Jan 24, 2011I have some data that I am putting on a treeview and have a checkbox on the page to decide if the user wants to order the nodes by date or type.
To do this I need to check if the code has already added a child node so when grouping by the type I don't put it in lots of times.
Lets say I have Type 1 and Type 2 and each have 3 items that would fall under these I want to achieve:
Type 1
Item 1
Item 2
Item 3
Type 2
Item 1
Item 2
Item 3
Instead of:
Type 1
Item 1
Type 1
Item 2
etc etc etc
I tried using the node.Contains function but it doesn't seem to exist (I am using c#).
